Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an amphipathic copolymer that does not require the use of additional colorant, excellent in transfer efficiency, a method for producing the same and to provide an amphipathic copolymer for toner-composition for electrophotography containing the same, a toner composition containing the copolymer and a method for producing the amphipathic copolymer. SOLUTION: The amphipathic copolymer comprises one or more S (solvatable) portions and one or more D (dispersible) portions, and has a chromophore covalently bonded thereto via a urethane, urea or amide linkage.
